INTELLIGENT KEY : CONSULT Function (BCM - INTELLIGENT KEY)INFOID:0000000009952502
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
SELF DIAGNOSTIC RESULT
Refer to BCS-52, "DTC Index".
